MACHINE .AND METHOD FOR MAKING `SHIN'GL'EQ.

rgnal No. 1,381,388, dated June 14, 1921, Serial No. 247.339, meri July 29, 1.918, issue nled October 28, 1921.

Be it known that I. l-lliNnY YVVLFF, a eitizen ot' the llnited States. and a resident of rit. Paul, in the eounty ol 'Ramsey and State of Minnewta. have in rented Certain neand useful improvements in Maeliines and Metliods for Making' Sliingrlee; of whieh the following" iS a speeiii'ation.

This maehine is'desigrued primarily for making shingles of the type shown in )atenl". to Silas M, Ford. No. 1207523. dated er. 5. i916, but provision is made for also using the inarliine for manufactoring;r shingles of the saine `general type without the reinforee nlent of the gutter walls.

(lne object oi in v invention is to provide in a machine for making` shingles.. traveling means for receiving a sheet of fiber and perform certain operations on the sheet While ity is in the traveling means. so .the sheet will be turned ont in a completed shingle strip.' i

Ut the incidental operations, one toprovide means `for Hitting and scoringr portions of the sheet as' it paeses through the machine. f

nother is to provide means for forming the edges oit' the ,futter upwardly.

Another provides improved means for forming this upward extension back upon the sheet in the Shape of reinforced edges for the. tahe so as to reinforce the gutter wail.. Y

Another object. is to provide means in the saine .inaiahine V.for blanking out. Strips of fiber eo ae to complete in the ber a shingle strip wviiout reinforced gutter wall.

lll/ith these and incidentai objects in View, the invention consistev ot' certain novei feanes of construction and combination of parte, the essential elemente of which are `lwreina'tter described with reference to the A drawing wha-h accompanies an d forms a part. of this specification.

ln the drawing Figure l is a side eleva-f tion. of niymaehine. Fig. 2 is. a. sectional View of the cutting and scoring die operating 'from the bottom, and the'forming die operating t'roni the top. Fig. 3 is a Sectional view showing-r two :fo-operating bars carrying flies. the-rein for makingr the unreshingle strip. Fig. 4 is an infor-ced type of enlarged. sectional detail showing a part of machine. Fig.

Fig. is e fragmentary bottom. view of the upper forming! die. Fig. 8 is a fra'gn'ientary pian 'View of the lower cutting and scoring: `die. Fig. 9 is a fragmentary detail of the bottom of a portion of a fiber sheety showing' the scoring-and cutting;u iines. Fig. 10 is ai Sec tional View of a portion showing the irs formation walls and Fig. 1l is asimilar the vonipleted 'formation of' the gut-ter View showing of the side gutter of a Shing-Ee' reinforced leut-ter Wall.

As shown in the drawings. a strip ot' Sheet material is drawn through the machine and a shing'ie'etrip is formed therefrom during the progress oi" the sheety through ihe mae ine.

Looking"r at. Fig'. the strip would be passed in troni the right and the bars 1 and 2 will seize and pali the strip firmly, the i'znetioa lining barely that of: pressure bars.

The han; E eaeh ycarry a forming die Such as 4 Fig. Q. and 'die hars 5 earry Cutting and scoring dies, sueh as l* ig,

The bars 1 and 3 are Amrried by the sprocket chain 7 running' over the sprocket wheels 8 and 9, and the here f2 and 5 are carried on the Sprocket chainfl() running over the sprocket wheels 'li i3 and 14 suitably jonrnaied on the 'frame i5 carry the siroeket wlieeis #l and 9 respectively, and similarly he shafts and 'i' also iournaled on tht. frame i5 ra-rrjy the sproeliet, Whe/ele 'H and. 12. I

- Gears it; and 1 9 serve to drive the shafts 13 and' 16 and these gears in turn ar f connected by pinione 20 and 2i one o5 which is tan-ned by any Suitable source o' power.

F rom the foregoing it will he eeen that the two chains carry hars whieh the dies are mounted, and also the preesa-le bars for holding the fiber. Mounted on the traine l5, are two cams and 23, adapted to operate the upper dies as will he hereina'er explained, and similarly earns 24 and Q6 are carried erate the lower dies. Guide members 2'? and y2e' likeWise/supported lloy the frame serve to press fthe two sets `of upper. and lower bars firmly against the'loer as these side 1 lili@ on the frame and serve 'to en bars pass between the guides, and dowel pins 29 registering with holes 30 are provided to positively line up the dies carried by the bars.A

Each of the cams is adjustably mounted on its support so the amount of camming accomplished by each cam and hence the effective movement of the dies-may be ad- A.justed for various thicknesses of fiber.

Looking at Figs. 4 and 5 it will be seen that the cam 22 is the first one t0 affect each of the dies 4 as the pass thereunder; this cam is so adjusted t at it will press downwardly each of the dies 4 as it passes thereunder so the lower surface of the dies will rest on the .ber sheet 31 as at 32.

While the die 4 is so positioned and the fiber sheet is passing to t e left, the cam 24 will move the co-operating die 6 upwardly will out completely through the'fiber sheet 31 as plainly shown in Fig. 4 at 32. i' The die 4 is then relieved as shown at 33 Fig. 5, and likewise the die @drops from the cam 24 and starts to ride up the cam 2 5, thus forming the edges 36 upwardly, the completion of this operation being shown at 34 Fi 4, and as the die 4 is no longer eld by t ve camit will be lifted up by the ie 6. I

.Aft the point'34 Fig. 4 the'dieG drops off the cam 25 and the die 4 is'pushed down,

wardly again, this time by'the cam 23, formi ving the up-turned edges of the fiber' 36, as

shown 't 35, Fig. 5.

The die 6 is again moved upwardly,lthis 'time bythe -cain 26, and by the time the upper surface of the die 6 meets the lower surface of the die 4, the die 4 has ridden past the cam 23 so that it may be pushed free of the ber and the die 6 sets the lower` edge of the fiber and then drops from the cam 26 and leaves the fiber in completed -'form as shown at 37 Fig. 5.

Theecams both being .free from the lfiber itis now delivered at 38 Fig. 1 in the shape of, a completed shingle strip.

The formation of the fiber at the point 32 Fig. 4`is shown in Fig. 9 the formation a. the point 34 is shown in Fig. 10, and the completed formation 'as at 37 Fig. v5 is shown in Fig. 11.

The dies 4 and 6 Fig. 6 are mounted in their respective bars 3 and 5 with a snug slide fit and the strips 38 and 39, preferablyof steel are suitably fastened to the dies, and screws 4G and 41 Amounted in the bars 3 and 5 respectively and passing through the strips 38 and 39 limitl the motion of the dies.

Adjusting screws 42 Figs. 4 and 5 are provided to adjust the height of the cams and h ence the effective lift of the dies.

When shingle strips are made having'the portions 43 and 44- 9 punched free from the sheet instead of scored andformed,v

the bars 3 are replaced by bars 45 in which are mounted knock-outs 46 Fig. 3 and the .43 and 44'Fig. 4 in a single piece, thus producing a shingle strip without reinforced gutter walls.

It is evident- .that only the cam 25 is required in -this operation, the other cams being removed. In the movement of strips of this type from left to right, the cam 25 operates the blanking punch, the knock-out being forced out of the female portion of the bars 45 by the punch, thus leaving the -punched out portion of the liber in the female portion of the bar-.45 below the knock-4 out- 46. so that the knife edges 33 land 3 4, Fig. 2

A. cam 48 Fig. l suitably mounted on the frame presses the knock-out downwardly and forces the punched out blank out of the die, letting it fall on the strip where it is nowfree from the machine.

While the shingle strips made on the machine with the replaced upper bars and replaced lower'punches, would have a gutter cut therein which would be' clean cut, it is preferable for certain-cases to form shingles having a deckled edge.

If this deckled edge is desired, the same punch 'is used as Awhen cutting the stra-ight unreinforced shingle strip, but the upper bars therein are changed so that-the female portion of the die is considerably larger than the male portion and a clean out isl not made but the material is roughly fractured giving the appearance as shown in Fig.` 12 and' lobviously-the material may be 'reversed in 105` the machine, and the deckled edge produced in the fiber rather than 'in ythe coating,'as shown. In this connection it is advisable to note that when the de'ckled edge is to be produced the material must be of a much more rbrittle nature than when shingle strips having reinforced gutter walls are being made. While I have described my invention and illustrated it in several designs, I donot wish it understood that I limitJ myself to g these constructions, as it is evident that the 1 application of the invention y be varied in 'many ways within the' scope of the following claims.V
